Figure 17. EVM Schematic
An optional circuit composed of Q08, Q09, Q10, R26, R27, R28, R29, R30, R31, R32, R33, and R34 can be
used to increase temperature coefficient of the trip current.
OUTPUT VOLTAGE SETPOINT CALCULATION
In the following calculation, assume the output voltage of SBRC1 (VO1), SBRC2 (VO2), SBRC3 (VO3), and LDO
(VO4) are 3.3 V, 5 V, 1.8 V, and 1.5 V respectively. The reference voltage and the voltage divider set the output
voltage. In the TPS5130, the reference voltage is 0.85 V, and the divider is composed of three resistors in the
EVM design that are R01A, R01B, and R05 for the first SBRC output; R03A, R03B, and R07 for the second
SBRC output ; R14A, R14B, and R11 for the third SBRC output ; R18 and R19 for LDO regulator output.
